Title: Fault detecting method for total region air-fuel ratio sensor
Inventor: KONDO TOSHIAKI
IPC: G01N27/26
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting a fault of a total region air-fuel ratio sensor for rapidly detecting a fault. SOLUTION: The method for detecting a fault of a total region air-fuel ratio sensor comprises the steps of supplying a constant current to an electromotive force cell 24 for an infinitesimal time at a predetermined period, detecting an internal resistance of the cell 24 from a voltage between electrodes 28 of the cell 24 at this time, and judging as a sensor fault when the resistance is out of a predetermined range. Since a resistance value is measured by applying the current to the cell interposed between an interval 20 of an atmosphere of a theoretical air-fuel ratio and an oxygen reference chamber 25 of predetermined oxygen concentration, the value can be accurately measured irrespective of the oxygen concentration in the measuring atmosphere.  And, since the fault of the sensor is judged based on the resistance value of the cell 24, occurrence of the fault of the sensor can be immediately detected.

Filed: 1989-03-15
Abstract: PURPOSE:To improve the processing efficiency by executing write of data after postponing write as for a data error of a bus caused by a temporary bus disturbance. CONSTITUTION:When an error of data is detected, write to a storage part 11 of the data is stopped, and thereafter, when the error is released within a prescribed time, write is restarted, and when the error is detected exceeding the prescribed time, the error generation is informed to a central processing unit (CPU) 10 in a state that write remains stopped, and a retry processing is executed by the CPU 10. Accordingly, even if a data error caused by a temporary bus disturbance due to an external noise, etc., is generated, since the error generation time is instantaneous, the error is not informed to the CPU 10, and write of the data is executed as it is. In such a way, the processing efficiency of a data processor is improved.

Abstract: PURPOSE:To reproduce a half tone, by switching in plural steps the highest temperature of a thermal head and therefore controlling the recording density of an object to the recorded by heat. CONSTITUTION:The applying voltage Vin is supplied to an input terminal. This voltage is then supplied to the inverted inputs of voltage comparators 20 and 21 via an analog switch SW1 and then a time constant circuit that is decided by a capacitor CS and a resistance RS. Here both CS and RS are equal to simulations of the synthetic heat capacity and synthetic heat resistance of a thermal head. The fixed levels of voltage equivalent to temperatures theta1 and theta2 are applied to the non-inverted inputs of the comparators 20 and 21 and then compared with each other. When the voltage Vin is high, the supply of an applying pulse is once stopped at a time point of the temperature theta1. Then the applying pulse is supplied again at a time point of the temperature theta2 and this supply is continued until the temperature theta1. This operation is repeated until the total applied energy reaches a prescribed level. Then the supply of the applying pulse is stopped by turning off the switch SW1.
